Dedicated phone numbers have been set up by police for anyone with information about the brutal murder of an 83-year-old man while out walking his dog in Norfolk.

Norfolk Police is now urging those information about the death of Peter Wrighton - who was stabbed in the head and neck in East Harling - to call 0800 056 0944 or 0207 158 0010 in a bid to fast-track their queries.

The lines are being manned by communications officers from Norfolk Constabulary and neighbouring forces.

In particular officers - who have already received more than 100 calls in three days - are keen to hear from people who were in the area between 9am and 11am on Saturday, August 5, the day Mr Wrighton was discovered.

Norfolk’s county policing commander, Chief Superintendent Mike Fawcett, said: “I would like to reassure the public that we are following several lines of enquiry and are pleased the public are supporting us in our investigation.

“We have received more than 100 calls in the last three days and we would continue to urge people with information, particularly those who were in the area between 9am and 11am, to make contact.

“I would like to ask again, that if you live within five miles of The Street please can you check your bins, gardens and outbuildings for any items which may have been discarded by a potential suspect.

“I hope residents will take some reassurance from the increased policing presence today which will be continuing throughout the evening and as long as is necessary, but I am aware that this incident will be causing some to worry. I would ask people to remain vigilant and to contact us if they see anything suspicious.”
